Hi,
I have a H710p controller in a 10 disk PowerEdge R720 server. The current controller suffers from an intermittent battery failure (happens about 1-2 times a year, the logs display a PERC battery failure and then the controller resolves to the normal state after 1 minute.
I'm told that the controller and battery must both be replaced. I have instructions from Dell on how to replace the physical controller, but what I'm not sure about is the exact steps to ensure that my RAID and disk setup remains intact after the upgrade process. Please can someone advise? I just need to make sure all the virtual disks and drive configurations remain in place after the upgrade.
Thanks
